Overview

Limited assessment

2 finding categories to review

LunaSpeak: AI Speaking Coach (com.growly.lunaspeak) was scanned at version 1.6.9 on 2026-10-09 but is not graded, because the analysis did not complete enough of its checks for a score to mean anything. The checks that did run recorded 2 finding categories across 2 occurrences; because the analysis did not complete, the absence of anything more severe is not a result. 20 tracking SDKs are present in the package, which describes what ships, not what runs or what it sends. This is static analysis of a single build: it does not observe the app running and does not establish that any data is exposed.

mediumcom.squareup.okhttp3:okhttp 3.12.13 — CVE-2021-03411 occurrence

Interpretation & review guidance

The app bundles a third-party library whose declared version matches a public security advisory (CVE). This is flagged from the version the library itself ships and a curated advisory list — confirm exploitability in your context and update the dependency to the fixed version. It is not a proof of live exploitation.

Evidence
1 recorded occurrence in the analyzed APK. These are distinct stored findings, not a count of every source match.

lowGoogle API key (client-shipped; restriction unverified)1 occurrence

Interpretation & review guidance

Android apps are designed to ship Google API keys in the client; Google restricts them by app signing certificate + enabled API. This is only a problem if the key is left unrestricted — presence alone is expected, not an exposure.

  • Persistent-identifier APIs referenced in code (Advertising ID (AAID), Android ID, Device ID / IMEI) with 17 analytics/ad SDK(s) present — the mechanism used for cross-app profiling.
  • Microphone data requested with third-party analytics/ad SDKs present.

This maps what the app can access (permissions it requests, identifier APIs its code references) to the third parties bundled in it. It reflects capability and SDK presence — not proof that a specific value was transmitted.

Data Safety comparison is not conclusive because analysis coverage is incomplete or unknown.
